Jacob Rees-Mogg is the honorary chief of the under-fire Oxford University Conservative Association

Arrogant young Tories ran riot at a prestigious university event where they allegedly groped women before going on to abuse pub locals.

The disgraceful behaviour came during a popular Port and Policy party run by the Oxford University Conservative ­Association, which has PM hopeful Jacob Rees-Mogg as honorary president.

Horrified students told how they saw sozzled men try to kiss and fondle women while downing up to 43 glasses of port each in boozing competitions.

Organisers who refused to serve the drunks more booze were shouted down with one reveller allegedly screaming: “I’ll buy their families.”

They then besieged the nearby King’s Arms pub and shouted “Buller, Buller, Buller” – a ­reference to the infamous ­Bullingdon Club society of boozing yobs.

The louts were also heard yelling at locals: “My castle’s bigger than yours.”

The braying mob also smashed glasses and bottles outside the building.

One outraged OUCA member said: “There is a culture of drunken and ­downright disgusting behaviour that has gone unchallenged for too long.”

OUCA could now face an investigation by university chiefs and one member has been suspended. It was also accused of turning a blind eye to the debauchery after previous allegations were made over fears it would attract bad publicity.

The Mirror has obtained a report presented to the association’s council by social secretary Lucy Boland which outlines the claims of drunken behaviour.

It said: “There is a common perception that the association has a problem with sexism, and that this perception is right.

“There are a number of members who feel able to treat women with disrespect and discourtesy.

“There have been numerous reports from members that last Sunday several attendees at Port and Policy groped, touched, kissed (or attempted to), or otherwise harassed female guests.

“We have also heard rumours of similar incidents occurring in previous weeks. I hope there is no doubt that everyone here today finds it totally ­unacceptable that women were made to feel uncomfortable in this way.

“When this issue was raised in the committee Facebook group chat, as well as by the Treasurer with senior officers, it was dismissed due to fears of bad PR.

“We believe senior members have been ignoring sexism and misogyny, not because they are themselves sexist, but they are worried about the public image of themselves and the association.

“Instead of trying to address the bad PR caused by this issue, we should be addressing the issue itself.”

OUCA President Timothy Doyle said tonight: “The association takes very seriously indeed all allegations of misconduct at its events.

“A member has been suspended until the end of term, following drunkenness at an event. Any allegations of sexual harassment are passed on to university authorities. No allegation received has been ignored.”

A university spokesman added: “All Oxford students are expected to treat the public and each other with respect.

“If students have behaved abusively or offensively, the university would be concerned and has powers to act.

“Where club activities are found to be in breach of disciplinary regulations, the university authorities may hold club officers or organisers responsible.

“Members of registered clubs are expected to treat other members with dignity and respect, discourage any form of harassment by making it clear that such behaviour is unacceptable.”

Theresa May and husband Phillip were members of OUCA when both at Oxford in the late 70s.

The Port and Policy events are held at St Giles Church Hall in Oxford every Sunday. Claims of disgraceful behaviour at previous events include a student ­allegedly being pushed off his bike before it was smashed in front of him and boozed-up members stealing a sign from inside a rival college before breaking it.

The scenes echo those in movie The Riot Club where aristocratic students at Oxford have an annual dinner in a pub that descends into drunken mayhem.

Club that churns out party chiefs

Oxford University Conservative Association has long been a conveyor belt for future Tory chiefs.

Founded in 1924, it has launched the careers of three PMs, four leaders and 13 Cabinet members. Theresa May and husband Phillip served on the committee.

Margaret Thatcher was OUCA president in 1946 as was Ted Heath in 1937. Other prominent ministers to join included Health Secretary Jeremy Hunt, former Foreign Secretary William Hague, and ex-Attorney General Dominic Grieve.

For some it is a family affair. Honorary president Jacob Rees-Mogg’s nephew Robert was president in 2017 and the Tory veteran’s dad William ran it in 1950.

In 2000, four OUCA members were expelled for making Nazi salutes. Bosses temporarily banned them from using Oxford University in its name in 2009 after two candidates made racist jokes at a hustings meeting.

Two years later four members resigned after singing Nazi songs which allegedly included the lyrics “dashing through the Reich…killing lots of kike” (A Jewish slur).

It was also revealed black cab rapist John Worboys was hired when he worked as a stripper to perform for them in 1989.
